Looking fron the bottom of the car this is the wire from the (R) headlight I use aluminium tape to keep the wires in place the wires run to the side of the ejector seat mechanism so they dont get snarled up

Here you can see the wires from the dashboard and speakers / pedals and (L) headlight all held by the wire clip

Run the tail lights between the frame and the boot floor.. This is to protect them from getting trapped

Run the Blue and Black cables under the frame and the rear seat and connect to the PCB note the position of the PCB White switch wire to the back of the car
